It’s a shock that Zac Posen‘s ZSpoke show this weekend actually went on. Insiders say Posen’s executive assistant, who also managed the designer’s p.r. for the past few months, quit a week before the show. Then his casting director walked out three days beforehand. Insiders described Posen’s show as “disorganized,” with some VIPs, including Claire Danes and Kristin Cavallari, not having seat assignments. A rep for the company, calling the show “fantastic,” said: “Several factors affect front-row seating and the art lies in accommodating last-minute attendees.”
